High temperature far infrared radiation coating

When the operating temperature of the heating furnace is 800°C, the heat transfer is dominated by radiation (90% or more). With the use of this product, the emissivity of the furnace body at high temperatures is increased from 0.35 to 0.88, and the heat absorbed by the furnace body surface is greatly increased. Far infrared radiation coatings have an emissivity of 96% at high temperatures, resulting in a significant increase in the temperature of the furnace furnace. The strong radiation material contained in the coating radiates far-infrared waves with strong penetrating power at high temperature, so that the molecules of the heated object absorb waves to generate energy level transitions, absorb energy uniformly and heat, reduce heating time, and fully save energy.

Features:

1. Safe, pollution-free and energy-saving, up to 20%

2. And high temperature resistance, excellent chemical stability, resistance to various kinds of atmosphere corrosion,

3. Has excellent heat radiation performance, radiation intensity and high replacement rate,

4. Excellent anti-erosion performance, fully protect the lining surface,

5. Keep the surface smooth and smooth at high temperatures.

typical application:

Technical performance indicators for refractory lining surface products of high temperature heating devices such as steel rolling furnaces, reforming hydrogenation furnaces, cracking furnaces, etc.:
